Amsco Integrated Algebra I: The Integers
 This is a free lesson from our course in Amsco's Integrated Algebra

 This lesson explains basic concepts of counting numbers, whole numbers & intergers. Counting numbers are also called natural numbers and are represented as 1,2,3,4,5... When we combine 0 with counting numbers, it forms the set of whole numbers. The integers are made of all the whole numbers and their opposites i.e. if a number is either a whole number or the opposite of this, then it's an integer… but still no fractions allowed. All the integers can be indicated like this: . . -4, -3, -2, -1, 0, 1, 2, 3, 4, . . . For example: -16, -3, 0, 1, 198. You’ll also learn here about the basics of- types of sets, the set and subsets of integers, ordering the integers, symbols of inequality etc. (More text below video...)

 (Continued from above)  Then it explains about the absolute value: the absolute value of a positive number is the number itself and the absolute value of a negative number is the opposite of the number (without regard to its sign). For example, 3 is the absolute value of both 3 and −3.

 As many of you know, Winpossible's online courses use a unique teaching method where an instructor explains the concepts in any given area to you in his/her own voice and handwriting, just like you see your teacher explain things to you on a blackboard in your classroom. This particular lesson includes the teacher's instruction, practice questions as well as end-of-lesson quizzes for practice. As we mentioned above, you can enroll in our online course in Trigonometry by clicking here. The format of Winpossible's online courses is also very suitable for teachers who are using an interactive whiteboard such as Smartboard on Promethean in their classrooms, because the course lessons can be easily displayed on such interactive whiteboards. Volume pricing is available for schools interested in our online courses. For more information, please contact us at educators@winpossible.com.
